WebApr 6, 2024 · Method 1: For k = 1, we can easily say that number of characters in string will be the answer. For k = 2, we can easily make pairs of same characters so we have to maintain the count of each character in string and then calculate sum = 0 for character 'a' to 'z' cnt = count (character) sum = sum + cnt* (cnt-1)/2 sum is the answer. WebI solved the problem below Binary String Problem in Hackerearth the problem which says "Given four integers x,y,a and b. Determine if there exists a binary string having x 0's and y 1's such that the total number of sub-sequences equal to the sequence "01" in it is a and the total number of sub-sequences equal to the sequence "10" in it is b."
